And the defeated leadership candidate suggested Labour should make a clear public apology for the failures of the previous government.

“There’s a debate in the Labour Party about how we should understand our record in government, what we should be proud of and what we should apologise for,” David Miliband told the Hindu Times in India.

“But I think it’s very important to be proud of your achievements and humble about your mistakes.”
